vim /Users/steve/.cargo/git/checkouts/virtio-drivers-4fdfaa862bcdc399/2b3c6cf/src/lib.rs

修改这个crate， 在lib.rs里添加 #![feature(renamed_spin_loop)] 就可以了

问题解决了么

在macos上使用github desktop，直接clone，会出现跟BraveY一样的错误；复制终端代理命令（临时）， 如下：（不同的代理客户端会有不同的端口号）

export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890 ， 然后clone到本地后，就可以正常跑了

执行代码为什么会跟代理有关系。

可能路径等配置未完善？需要用terminal clone到本地根目录才能跑起来

或者你在你直接把包放到根目录下试试
